Abstract
Golf balls include dimples for generating a turbulent boundary layer. At least some of the dimples include a fan-shape. The fan-shaped dimple has a plurality of blades. Each blade has a trailing edge flush with a land area of a spherical surface of the golf ball, a leading edge, and a side wall connected to the leading edge. The dimple also has a sloped floor extending from the trailing edge to the leading edge, a blade tip connecting the leading edge to the trailing edge at a distal end of the blade, and a blade root connecting the leading edge to the trailing edge at a proximal end of the blade.
